DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] Please refer to Figure 1-Figure 5 This embodiment is basically the same as the first embodiment. This embodiment is made on the basis of the first embodiment and has the same beneficial effects as the first embodiment. The same parts can be referred to each other and will not be described in detail here.

[0027] A fascia gun motor assembly, the fascia gun comprises a fascia gun housing 1 and a motor body 2 arranged in the fascia gun housing 1, the motor assembly comprises a mounting base 3 for carrying the motor body 2 and a cooling fan 4 for accelerating the heat dissipation of the motor body 2, four limit blocks 301 are symmetrically fixed on the mounting base 3, an extrusion block 302 used in conjunction with the four limit blocks 301 is fixed on the inner wall of the fascia gun housing 1, an extrusion plate 303 is arranged below the two limit blocks 301 on the same side, the extrusion plate 303 is fixedly connected to the extrusion block 302 by a locking screw, and a shock-absorbing pad is fixedly arranged on the outer side of the middle part of the extrusion block 302;

[0028] The heat dissipation fan 4 is fixedly connected to the fascia gun housing 1 through a mounting assembly, and the mounting assembly includes a mounting ring 401 arranged in the fascia gun housing 1, and the mounting ring 401 is fixedly arranged on the upper part of the fascia gun housing 1 through a plurality of support plates 402, and the heat dissipation fan 4 is fixedly arranged in the mounting ring 401;

[0029] The specific installation method of the motor body 2 is as follows: first, fix the motor body 2 to the middle part of the mounting base 3 by means of positioning screws, and then place the motor body 2 and the mounting base 3 as a whole into the fascia gun housing 1. When placing the motor body 2, it is necessary to place the motor body 2 upside down and vertically so that the tail of the motor body 2 is inserted into the interior of the upper heat dissipation shell 101. After the motor body 2 is placed in, the limit blocks 301 on both sides of the mounting base 3 are inserted into the middle part of the two extrusion blocks 302. At this time, the mounting base 3 can be fixed to the connecting column inside the fascia gun housing 1 by means of a soft connection. Finally, the extrusion plate 303 is fixedly connected to the extrusion block 302 by means of locking screws. At this time, the two limit blocks 301 and the extrusion plate 303 form a U-shaped limit structure on the side of the mounting base 3 and then surround the extrusion block 302. That is, the extrusion block 302 is set to effectively limit the torsion generated by the mounting base 3 and enhance the strength of the soft connection.

[0030] Furthermore, the air outlet center axis of the cooling fan 4 coincides with the upper end surface of the mounting base 3. The cooling fan 4 fixedly arranged above the interior of the fascia gun housing 1 can ensure that the fresh air blown out from the cooling fan 4 can be directly blown to the middle of the motor body 2, thereby ensuring the necessity of heat dissipation of the motor body 2.

[0031] Furthermore, the thickness of the limiting block 301 is smaller than the thickness of the mounting base 3 . This arrangement method can facilitate the extrusion of the limiting block 301 by the extrusion plate 303 , thereby improving the coordination between the limiting block 301 and the extrusion block 302 .

[0032] Embodiment 2

[0033] Please refer to Figure 2-Figure 6 A fascia gun motor also includes a heat dissipation assembly, the heat dissipation assembly includes an upper heat dissipation shell 101 fixedly arranged above the fascia gun housing 1, and the tail of the motor body 2 is placed inside the upper heat dissipation shell 101;

[0034] Two groups of cooling fins 201 for use with the cooling fan 4 are fixedly provided in the middle of the motor body 2, wherein one group of cooling fins 201 is composed of a plurality of U-shaped cooling fins 2011 which are gradually enlarged from top to bottom, the middle of the U-shaped cooling fin 2011 is horizontally arranged, and the two ends of the U-shaped cooling fin 2011 are vertically arranged; wherein the other group of cooling fins 201 is composed of a plurality of vertically arranged rectangular cooling fins 2012, and the plurality of rectangular cooling fins 2012 are evenly distributed.

[0035] The gas flow route inside the fascia gun housing 1 is as follows: when the cooling fan 4 is working, the cooling fan 4 sucks in the fresh air from the rear side and blows it out from the front side of the cooling fan 4. Since the cooling fan 4 is arranged above the interior of the fascia gun housing 1, the fresh air blown out will directly impact the middle part of the motor body 2, and the windward surface of the motor body 2 is provided with a plurality of U-shaped heat sinks 2011 of different sizes, and the middle part of the U-shaped heat sink 2011 is arranged horizontally, and the two ends of the U-shaped heat sink 2011 are arranged vertically, which results in the fresh air from the front After the wind enters the arc-shaped channel formed by two adjacent U-shaped heat sinks 2011 formed by the cooling channel formed by multiple U-shaped heat sinks 2011 of different sizes, the forward direction will change, and the flow direction of the fresh air will change from the original horizontal direction to the vertical direction, so that the fresh air will blow through the middle of the motor body 2 and then move to the inside of the upper heat sink 101. Since multiple air holes are opened on the top of the upper heat sink 101, the fresh air that has undergone heat exchange will be discharged from the air holes. This forced heat dissipation method is much more effective than traditional natural heat dissipation.

[0036] The fresh air flow that does not directly impact the windward surface of the motor body 2 will impact the interior of the fascia gun housing 1, and the fresh air that enters and passes through the entire fascia gun housing 1 will move upward from the rectangular heat sink 2012 on the leeward side of the motor body 2. These fresh air will also move upward along the rectangular heat sink 2012 and then enter the interior of the upper heat dissipation shell 101 and be finally discharged. During the whole process, the gas inside the fascia gun housing 1 will cool down the entire motor body 2, and can also force the heat dissipation of the outer shell of the motor body 2, thereby ensuring the long-term use of the fascia gun housing 1 and greatly increasing the actual service life of the fascia gun.

[0037] Furthermore, the width of the U-shaped heat sink 2011 is equal to that of the rectangular heat sink 2012. Firstly, the equal width of the U-shaped heat sink 2011 and the rectangular heat sink 2012 can ensure the controllability of the size of the entire motor body 2, which is convenient for being placed inside the upper heat dissipation shell 101. At the same time, the equal width of the two means that the cross-sectional area of ​​the heat dissipation channel formed is the same, which is convenient for the flow and discharge of the entire gas.

[0038] Furthermore, the inner wall of the fascia gun housing 1 is provided with a plurality of arc-shaped air inlets for use with the heat dissipation fan 4 , and a plurality of air holes for ventilating are provided at the top edge of the upper heat dissipation shell 101 .

[0039] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0041] Each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments.
